Donkey Punch Trailer?

I've heard of the "Donkey Punch". But I hadn't heard someone had made a movie, and assigned that sexual act as the title. Right off the bat I thought I was going to see a trailer for a sex comedy . . . but oh was I wrong. From the looks of it, we're looking at a few young, British, people that partied just a little too hard and got themselves in over their heads. Like murder over their heads. So, they go and do what most people that are faced with murder do. And that would be . . . committing more murders to hide the first accidental one. Check out the trailer. I'll probably end up buying this just for the title. I won't even watch it maybe.
